0W-20 vs 5W20 Warranty Question

Hello guys,
Apologies for the late response. I just came home from work.
Wow! I'm totally overwhelmed by the replies. I really appreciate it guys! A whole lot of new things I just learned.
Anyway, for the oil, yes, it's a 5W-20 fully synthetic oil, API SN, ILSAC GF-5. it used to have a Dexos1 logo on the bottle but it's now gone. I asked our top management about the Dexos1 logo and they said their license had expired, and the oils we have (5w30 & 5W-20) still contains the same formulation, and until now they are hesitating to renew the Dexos1 license due to it being expensive.
The oil filter used was an AC-Delco PF48.
Our Area Manager then met with the technical engineer from the dealer and the engineer told him that only 0W-20 is to be used and no other viscosity. Otherwise, warranty claims would be denied.
We then checked with our lab engineer and this is what he stated(pasted):
Quote:
Newer engiens are made to VERY VERY exacting tolerances inside them and they REQUIRE the new synthetic 5W_20 engine oils to match the small spaces between rings and engine bearings. The NEWER "0" series oils are JUST a bit better and more refined, and protect the engine at start-ups in the MOST cold weather only, and also can be a WEE bit more fuel efficient. As far as I have been told or read, ALL 5W-20 oils are synthetic or partial synthetic oils. 0W-20 is Full Synthetic and will actually get you MORE power and fuel mileage with time, and SOON many oils will feature this NEWER oil as a standard for fuel economy. It is AHEAD of it's time in many ways
So, we where surprised about his response which did not even tackle anything about the issue. (Actually we were expecting him to say "OK, there's no issue with 5W-20 vs 0W-20 etc, but he just copied it from API)
Thanks again for the support!

5w-20 is lighter than 0w-20 when hot, so the problem here is using an oil slightly thinner at temperatures above 100 deg C.

Not sure 5w-20 is thinner than 0w-20 at high temps. I think your comment is based on 0w-20s typically having a higher viscosity index, but VI is a simple equation showing the change in viscosity between 40C and 100C. How oils behave outside of this range is not linear. A better comparison would be HTHS viscosity; typically 5w-20s are are same or slightly higher than their companion 0w-20 weights.

I hesitate to use HTHS since that's done under high shear conditions. KV150 would be better to look at since it defines hydraulic (low-shear) performance, but we don't have KV150. We do have KV100, which defines the "20" number (J300), yet oil gets hotter than that sometimes, as in 121 deg C (250 deg F).
More VI in the oil actually does keep the oil from thinning out as much when very hot (say 121 deg C). There was something in a Formula1 racing tech article I once read where they mentioned it was especially important to have a decent VI oil to keep their hot engines from thinning the oil. Anyway, VI does keep the oil thicker in hot engines.

Why would you be hesitant to use HTHS, when that's what is doing the lubrication in the bearings, rings, and piston skirts at anything much above idle ?
Yes, VI matters, but it's the High Shear VI that we should be understanding...KV VI may have little meaning other than direction in that sphere.
I've been trying to find High Shear Viscosity Index, and while tantalizingly close to something comprehensible on occasion am still in the wilderness.
If F1 have a VI focus, it will certainly be on High Shear, not KV grounds.

Shannow, HTHS matters like you say. Here, I think GM is worried about hydraulic operation of the displacement on demand and/or VVT kind of machinery, not so much HTHS.
HTHS is about the same in a full synthetic 5w-20 and a 0w-20, covering the case of bearings, etc., like you say. That can't be GM's worries.

I say its time to switch oils and have oils available for what cars require.

It's still your best measure for operational viscosity at operational temperatures, far better than any KV. Remember that you can have a 40 grade with an HTHS of around 3, which is why SAE J300, not to mention API diesel specs, started incorporating HTHS. It's also very relevant to fuel economy.
And yes, F1 cars won't be looking for fuel economy gains when the oil is cold and thick. They'll be looking to ensure the oil doesn't thin too much at operating temperatures. That's the aspect of high VI they'll be seeking.

Again, for hydraulic operation of the valvetrain variable timing and/or DOD system, what matters is how the fluid behaves in a KV test, not an HTHS test.
Can't find the reference now, yet there was something different about the way the VII chemistry reacted to high shear which makes HTHS a separate issue from KV. Of course we see that all the time in oils that have a KV100 of X and an HTHS of Y, and X&Y are different for different basestocks and VII treat.

X and Y are also Cst and Cp, which will have different numerical values also.
Yes, hydraulics play with the KV...but they work satisfactorily over a range of many hundreds of Cst, the fraction of a cst bewtween a 0W20 and 5W20 above 100C is absolutely meaningless to their operation.

Usually, though, you're going to find HTHS deficient, and not KV. How often have we come across problems where the KV was up above where it "should be," even by a whole grade? Being a little low on KV is part of the risk of choosing an ILSAC rated grade, especially when it comes to 30s. They're already at the low end of the 30 spectrum.

I guess it is best to inform all branches to be aware of the recommeded oil. We still don't have a 0W-20 grade. And I'm hoping that this issue would make our plant engineers to manufacture or the sales department to acquire a different brand but with the 0W-20 viscosity otherwise, we would be losing a lot of customers.
Thank you for the manual.

Yep, will advise the management. We actually have other brands and grades of oil, however, nobody really thought that a "20" would be required to be used here in Saudi Arabia. Although we have our own 5W-20.
For example, I've seen a KIA manual wherein they specified a 5W-20 but on the bottom of the page they placed a note saying that if you are in the middle east, a thicker grade shoud be used(dealer recommends 10w30 at least). And one time I contacted a retailer for a 5w30 oil and he said that they don't carry 5w30, only 5W-40 due to weather conditions here in Saudi Arabia.
Keep it goin' guys! From the posts in this thread, I can say is that I've learned a lot!

All of this viscosity stuff is interesting but a shop should run what the manufacturer recommended. I don't care how many threads you read on BITOG that doesn't excuse running the incorrect oil. You can't become more knowledgeable than the manufacturer by reading BITOG and the potential liability that could come from it. Unless your shop is willing to offer a powertrain warranty with each oil change.....

Thank you for the manual.
Oh you're welcome, it was an easy find.
I do find it peculiar that a legitimate dealership doesn't even have the proper grade of oil for the vehicles they service, but I guess since you said 0w-20 is nowhere to be found where you live, it might be that they just can't find a source to get it.

I guess it is best to inform all branches to be aware of the recommeded oil. We still don't have a 0W-20 grade. And I'm hoping that this issue would make our plant engineers to manufacture or the sales department to acquire a different brand but with the 0W-20 viscosity otherwise, we would be losing a lot of customers.
Thank you for the manual.

The dealership actually has the oil, the company I work for has a chain of quick lubes, and we don't have the oil. Although we carry different brands of oil, not even one of them is a 0W-20.
Sad to say also that being an oil company, we should have seen that coming.
